A baby’s bad cough is usually caused by foreign body inhalation, disease and other factors, and symptoms can usually be relieved through emergency measures, medication and general treatment.1. Emergency measures: For when pollen, atmospheric particles, dust or other foreign bodies are accidentally inhaled into the airway, coughing may be induced when the mucous membrane of the respiratory tract is affected by foreign body stimulation. At this time, you can try to pat your baby’s back to remove the foreign body. For larger foreign bodies, they need to be removed by professional means under the operation of a doctor. 2. Medication: Babies with colds, pharyngitis, rhinitis, bronchitis, allergies, asthma, respiratory malformations, bronchopulmonary cysts, mediastinal tumors, ciliary dyskinesia, gastroesophageal reflux and other diseases are more likely to have a strong cough. Coughs caused by colds can be treated with drugs such as pediatric cold granules. For children with cough variant asthma, bronchodilators and antihistamines should be used as prescribed by the doctor to relieve bronchospasm and coughing; coughs caused by inflammatory reactions can be treated with antibiotics for anti-inflammatory treatment and catecholamines to help dilate the bronchi. For coughs caused by gastroesophageal reflux, they can be treated with H2-blockers, mucosal protectants, proton pump inhibitors and, if necessary, nebulized inhalation therapy.3. General treatment: You should pay attention to warmth, rest and room ventilation in daily life. Try to use liquid or semi-liquid food, such as thin porridge and rice soup, and take vitamin supplements in appropriate amounts, eat more vegetables and fruits and drink more water. For the choice of medicine for cough medicine for babies, it is recommended to do so under the guidance of a doctor. Moreover, if you only pursue quicker cough relief, it is not good for your baby’s cough recovery. You should actively look for the cause of your baby’s cough and treat it according to your actual situation.
